Product Description

ASTM B111 C44300 Heat Exchanger SMLS Tube

ASTM B111 C44300 seamless tubes are high-performance tubes made from Admiralty Brass, a copper-zinc alloy with small additions of tin and arsenic. This alloy is specifically designed to provide excellent corrosion resistance in high-moisture environments, particularly in applications involving seawater and other mildly aggressive conditions. C44300 tubes are known for their durability, anti-fouling properties, and outstanding heat transfer efficiency.

Key Features of C44300 Seamless Tubes:

1. Corrosion Resistance:

The addition of tin and arsenic enhances resistance to dezincification and stress corrosion cracking, making these tubes suitable for seawater and brackish water applications.

2. Seamless Construction:
The seamless design eliminates weak points, ensuring uniform strength and long-lasting performance under high-pressure and high-temperature conditions.

3. Thermal Conductivity:
C44300 has excellent thermal conductivity, making it ideal for heat exchanger and condenser applications where efficient heat transfer is crucial.

4. Durability:
The alloy is resistant to biofouling, pitting, and erosion, ensuring a longer service life in aggressive environments.

5. Mechanical Strength:
C44300 provides good mechanical strength and ductility, allowing it to perform reliably in demanding conditions.

Chemical Composition:

Grade	Cu	Sn	As	Zn
ASME SB111 C44300	70–73%	0.8–1.2%	0.02–0.06%	1.0% max

Mechanical Properties:

Grade	Yield Strength	Tensile Strength	Elongation
ASME SB111 C44300	≥ 105 MPa (15 ksi)	≥ 310 MPa (45 ksi)	≥ 30%

Common Applications:

· Heat Exchangers and Condensers: Widely used in power plants, chemical industries, and HVAC systems.

· Marine Applications: Perfect for desalination systems, ship cooling systems, and other seawater-based equipment.

· Industrial Equipment: Used in evaporators, distillers, and other systems requiring efficient heat transfer in corrosive environments.

· Piping Systems: Suitable for brackish and seawater piping systems due to its resistance to corrosion.

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.

As an engineer in Siberia, I tested these fin tubes in extreme cold (-30°C). The ASTM A213 T11 steel performed well with no thermal cracks, and cooling efficiency met expectations (88%). That said, the Russian-language documentation had translation errors in technical terms, causing minor confusion during installation.

We checked a few before installation — wall thickness consistent, roundness good. Welded in without problems.
